Fig. 3 is aview, partlyin side elevation between the tanks established by means tion and vertical section, of the air-equalizing of a pipe 0 as illustrated in Fig. 5, in which device arranged in the system of piping becase the pipe 0 is in direct communication tween the air storage or receiving tank and with the valve-chest of the engine and the 5 the air-compressor. Fig. 4 is a plan view of tank 0. A suitable valve 0 can be placedin a truck, compressors thereon, and the air-resaid pipe (see Fig.1) in order to shut off the ceiving tanks with their connecting-pipes and supply of air to the engine, if necessary.

Each air receiving or storage tank 0 and O can be provided with a blow-off or refilling cock 0 an air-gage 0 and a safety-valve 0.

At any convenient point in the pipes a and c we have arranged the air-equalizing devices F, which are adapted to act automatically to relieve the pressure of air in the tanks 0 and O and to cause the air-compressors on the truck to exhaust the air to a point outside of said tanks. This equalizing device F, as will be seen from Fig. 3, consists of a cylinder f, in which is arranged a suitable slide-valvef', provided with suitable air-passages f and f This cylinder f and the passages f in the valve f normally establish a direct communication through said passage and the two sections of the pipe between which said cylinder is arrangedfor the air from one of said compressors to one of the air-storing tanks. Said cylinder f is provided at its lower portion with a small air-chamberf which is in direct communication by means of a pipe f with the air receiving or storage tank. At a point gin said pipes c and c is a T-joint from which extends a pipe g, which leadsinto said valve-cylinderf, directly in front of the solid portion of said valve above the passage f therein. Directly opposite in the cylinder f we have secured an exhaust-pipc g Thus when the compressors or pumps B and B are in operation there is an unobstructed passage through the pipes c and 0 through the equalizing devices 1 into the two tanks 0 and C, filling said tanks and the air-reservoirf; but the valve f is so balanced that when the air in said tanks reaches a maximum pressure the valve f will be raised, thereby obstructing the passage through the pipes a and c and establishing a direct passage for the air through pipe g, passagef in the valve, and through the exhaust-pipe 9 as will be clearly understood from said Fig. 3. As soon as the air contained in the tanks 0 and G is withdrawn by the engine D the pressure becomes lowered and the valve f drops automatically to its normal position, again opening communication with the pipe 0 or the pipe 0 A springf may be arranged above said valve, if desirable, to counteract the upper passage of'said valve and help to force it back to its normal position within the cylinder f.

From Figs. 1 and 2 it will be evident that we may arrange upon the roof of the car the air-receiving tanks or reservoirs H and H, which are in communication with the tanks 0 and O by means of the pipes 7L and h, placed in any suitable position on the car.

The operation of our system is as follows: The pumps or compressors B and B on the truck are caused to force the air into the re ceivers or tanks C and C by means of the intermediately-arranged eccentrics operated by the revolutions of the car-axle. While the train is in motion, the tanks 0 and O and the tanks H and H, when the latter are used in connection with the system, become sufficiently filled with air, in which it is compressed and stored, and when needed to drive the engine D can be drawn therefrom by opening the valve o It is of great advantage to carry a number of air-receiving tanks connected with each other, whereby the pressure becomes equalized and will give a store of power of sufficient energy to drive the engine and dynamo when the train stops, and thereby maintain a current which will keep the lights burning for more than three hours. Of course we may use the storage-batteries, which can be filled by the operation of the dynamo and can be used in case of any nnforseen break to the engine or any other parts of our system; but it is our intention to use them only when absolutely necessary.

It very often happens that when trains are made up at the terminal stations they stand for hours in the depot. Therefore in order to charge the tanks C and C with compressed air each tank is provided with a cook or nipple 0 to which can be attached a tube, and compressed air can be forced into the tank from a small plant located in the vicinity of the station.

Having thus described our invention, what we claim is- 1. The herein-described system for electrically lighting cars, consisting, essentially, of the combination, with a pivoted truck, of an air-compressor on said truck, means for driving said air-compressor from the axle, consisting, essentially, of eccentrics rotating with and arranged on the axle and connected with the air-compressor, an air-engine and dynamo connected therewith, an air receiver or storage-tank -intermediately arranged between said compressor and air-engine, and a pressure-regulator arranged in the piping between said compressor and air-receiver, acting automatically to shut off the air from the compressor into said air-tank and cause the compressor to exhaust outside of the tank, and a flexible tube connection in the piping between said air-compressor and the regulator, sub stantially as and for the purposes set forth.
